摘要
Luminescence of Tb3+ doped MO (M=Ca,Sr) were investigated. Photoluminescence of MO:Tb3+ (M=Ca, Sr) is due to the 5D4,3-7FJ transitions of Tb3+ ions. Under UV light irradiation, the strongest luminescence peak of SrO:Tb3+ located at 543 nm while the CaO:Tb3+ located at 550 nm. Long-lasting phosphorescence of MO:Tb3+ (M= Ca,Sr) were also observed with naked eye even after the 254 nm UV irradiation have been removed. Thermolumi- nescence (TL) spectra revealed that the incorporation of the Tb3+ formed a highly dense trapping level located at a suitable depth in relation to the thermal release rate at RT to creat the long-lasting phosphorescence.
Luminescence of Tb^3＋ doped MO （M=Ca,Sr） were investigated. Photoluminescence of MO：Tb^3＋（M=Ca, Sr） is due to the ^5D4,3-^7FJ transitions of Tb^3＋ ions. Under UV light irradiation, the strongest luminescence peak of SrO：Tb^3＋ located at 543 nm while the CaO：Tb^3＋ located at 550 nm. Lng-lasting phosphorescence of MO：Tb^3＋ （M= Ca,Sr） were also observed with naked eye even after the 254 nm UV irradiation have been removed. Thermoluminescence （TL） spectra revealed that the incorporation of the Tb^3＋ formed a highly dense trapping level located at a suitable depth in relation to the thermal release rate at RT to creat the long-lasting phosphorescence.
